Hello Marcus and Carsten, First of, we also do need debugging symbols in release builds.
Microsoft writes on https://msdn.microsoft.com/en-us/library/windows/desktop/ee416349(v=vs.85).aspx "You also need to take steps to maintain full compiler optimizations while generating symbols." - set Debug Information Format to Program Database (/Zi). - set Generate Debug Info to Yes (/DEBUG). - set References to Eliminate Unreferenced Data (/OPT:REF). - set Enable COMDAT Folding to Remove Redundant COMDATs (/OPT:ICF). That reference initiated my initial change of the code generation of all of our libraries and executables since we have started to generate memory dumps on crash in release code. The flags are detailed on https://msdn.microsoft.com/en-us/library/bxwfs976(v=vs.120).aspx /OPT:REF eliminates functions and data that are never referenced; /OPT:ICF to perform identical COMDAT folding. Redundant COMDATs can be removed from the linker output. Usage of /OPT:REF implicitly sets /OPT:ICF. Usage of /Zi /DEBUG implicitly sets /OPT:NOREF /OPT:ICF is controversial. Microsoft recommends to use OPT:NOICF to preserve identical functions in debugging builds. "If /DEBUG is specified, the default for /OPT is NOREF, and all functions are preserved in the image. To override this default and optimize a debugging build, specify /OPT:REF. Because /OPT:REF implies /OPT:ICF, we recommend that you also specify /OPT:NOICF to preserve identical functions in debugging builds. This makes it easier to read stack traces and set breakpoints in functions that would otherwise be folded together. The /OPT:REF option disables incremental linking."

Probably the /OPT:REF /OPT:NOICF is the better combination. Finally, I think that best we should create some cmake options for that, so that nobody is negatively affected. Then we can experiment a little with these settings and see what is best. What do you think, Best, Johannes ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Opensg-users mailing list Opensg-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/opensg-users
